This paper illustrates the application of a BEM crack formulation to slope analysis. The formulation requires only hypersingular equations defined at collocations placed along the crack line. The integral equations are derived from the corresponding ones used to model smeared non-linear behaviours, but finding the limit when the dissipation zone width goes to zero. The crack element is used in this work to enforce the stress state along slip surfaces to obey a particular elastoplastic criterion. For simplicity, the well-known coulomb model has been adopted to analyse 2D and 3D examples. The results are compared with those obtained by using classical limit equilibrium methods.
